XD-677 Added flag to parser to ignore referenced resources

Added a parameter in XDParser.parser to not call to ChannelNode.resolve() if false.  This fixes the problem, but I have some concerns about exposing that parameter to the parser interface because setting it to false must be done with extreme caution. A lot of the StreamCommandsTests failed until I put in the check that we are undeploying a tap in AbstractDeployer.
